So, Kinemon and now Zoro have been shown to be able to use Foxfire style. While it has mostly been shown to be useful in cutting through fire, hasn't it also been shown to allow the user to produce flames as well? I'm pretty sure when Zoro used Hiryu Kaen on the rooftop he said "flame rend" and then produced flames from his sword? Is that not what happened? If he did, how tf does this work?
